I just bough a bottle of tetra cleanse. How many a day should i take in order to p a drug test?

*Please, if your going to put me down don't even answer.that's not why I'm asking this question* now for the question, how many a day should I take to get pot out of my system? I smoked a joint 5 days ago and havent smoked since, I've been taking a similar herbal cleaner and lots of water but I've run out of the cleanser today. I bought a home pot test and did it and I came up dirty still,so I bought some Tetra cleanse today and I want to know how many should I take a day in order to get clean. People who have used tetra cleanse please tell your story and how it worked for you. And for the last time , don't answer if your just going to write "just don't do drugs" I understand that, I just want to get clean for a job in three days. I'm trying to change my life you know.
